Shimano XTR RD-M9100 Cable Fixing Bolt Unit

No, this specific fixing bolt unit is engineered exclusively for the Shimano XTR RD-M9100 rear derailleur. It is not cross-compatible with other Shimano series, so please verify your derailleur model before purchasing.

The RD-M9100 uses a specific clamping interface designed to hold the shift cable securely without damaging the cable strands. A generic bolt may not provide the correct torque or clamping surface, which can lead to cable slippage or premature wear.

This is a complete cable fixing bolt unit, which includes the necessary hardware to secure the cable to the derailleur body as specified by the original factory design.

You will need a standard hex key, typically a 4mm or 5mm depending on your specific setup, to install the bolt. Be sure to use a torque wrench if possible to avoid overtightening and damaging the derailleur threads.

You should replace the bolt if the hex head is rounded off, the threads are stripped, or if you notice the cable slipping despite being tightened to the correct torque. If the bolt shows signs of corrosion or deformation, it is best to replace it to ensure consistent shifting performance.
